Measurement of -Tocopherol Turnover in Plasma and in Lipoproteins Using Stable Isotopes and Gas Chromatography/Mass Spectrometry

As the primary fat-soluble antioxidant in human tissues, α-tocopherol absorption and metabolism have been the focus of active investigation, as reviewed recently (1 ,2 ). Although the concentration of any metabolite measured in plasma

to the prevention of age-related diseases. Oils extracted from plant seeds are known to contain various lipophilic antioxidants such as vitamin E (α-tocopherol) and carotenoids. They are known to not only decrease serum low-density-lipoprotein (LDL) level
